What is the primary goal of guided tissue regeneration (GTR) in the anterior gingiva?
Show answer and explanation
Correct answer: B. Regeneration of the lost periodontal attachment (PDL, cementum and alveolar bone)
- A. Epithelial coverage is exactly what GTR's barrier membrane EXCLUDES, because fast epithelium prevents true regeneration.
- B. Correct. GTR uses a barrier to allow slower PDL/progenitor cells to coronally repopulate the root, regenerating cementum, PDL and bone.
- C. Debridement is part of surgery but not the regenerative goal of GTR.
- D. The membrane maintains space temporarily; the goal is biological regeneration, not a permanent foreign body.
